Delta Faucet Repair

I have been attempting to repair a leaky Delta Classic batroom tub faucet. This WE I replaced both the springs and rubber bushings, then, when the drip did not stop, I replaced the valves (Delta Type C) themselves. The leak is now worse. What alternative repairs are there?

Is this a two handle or a one handle faucet. I'm guessing that you replaces "stems" and that's good. There are two sets of springs and washers that come in kits. Some kits have one kind or the other, and there not interchangeable. Some kits have both kinds....Buy the kit marked with the Delta logo and not an off brand.

Also try rolling up a piece of emery cloth and sand the hole that the washer and spring fit into before reassembly.

Deltas are not usually troublesome like this. If the faucet is pre-1972 it uses the longer cylindrical spring, and post72 uses the short tapered spring. I sometimes carefully stretch the spring just slightly.
